And the rest of the fight has plenty of differences.
It's also not a transition phase, it's phase 2 with a DPS check. Byakko schmup style dodging is a transition phase, Suzaku DDR stuff is a transition phase, Seiryu's water bit is a transition phase (though a short one). Anything, like the aforementioned Omega Level Checker, that requires execution to not fail is simply another regular phase of the fight.
